public class StackedAreaChart<X,Y> extends XYChart<X,Y>
StackedAreaChart is a variation of AreaChart that displays trends of the contribution of each value. (over time e.g.) The areas are stacked so that each series adjoins but does not overlap the preceding series. This contrasts with the Area chart where each series overlays the preceding series. The cumulative nature of the StackedAreaChart gives an idea of the total Y data value at any given point along the X axis. Since data points across multiple series may not be common, StackedAreaChart interpolates values along the line joining the data points whenever necessary.
Since:
JavaFX 2.1

    • StackedAreaChart

      public StackedAreaChart(Axis<X> xAxis, Axis<Y> yAxis)
      Construct a new Area Chart with the given axis
      Parameters:
      xAxis - The x axis to use
      yAxis - The y axis to use

    • StackedAreaChart

      public StackedAreaChart(Axis<X> xAxis, Axis<Y> yAxis, ObservableList<XYChart.Series<X,Y>> data)
      Construct a new Area Chart with the given axis and data.

      Note: yAxis must be a ValueAxis, otherwise IllegalArgumentException is thrown.

      Parameters:
      xAxis - The x axis to use
      yAxis - The y axis to use
      data - The data to use, this is the actual list used so any changes to it will be reflected in the chart
      Throws:
      IllegalArgumentException - if yAxis is not a ValueAxis

      Parameters:
      value - the value for the createSymbols property

    • dataItemAdded

      protected void dataItemAdded(XYChart.Series<X,Y> series, int itemIndex, XYChart.Data<X,Y> item)
      Description copied from class: XYChart
      Called when a data item has been added to a series. This is where implementations of XYChart can create/add new nodes to getPlotChildren to represent this data item. They also may animate that data add with a fade in or similar if animated = true.
      Specified by:
      dataItemAdded in class XYChart<X,Y>
      Parameters:
      series - The series the data item was added to
      itemIndex - The index of the new item within the series
      item - The new data item that was added

    • dataItemRemoved

      protected void dataItemRemoved(XYChart.Data<X,Y> item, XYChart.Series<X,Y> series)
      Description copied from class: XYChart
      Called when a data item has been removed from data model but it is still visible on the chart. Its still visible so that you can handle animation for removing it in this method. After you are done animating the data item you must call removeDataItemFromDisplay() to remove the items node from being displayed on the chart.
      Specified by:
      dataItemRemoved in class XYChart<X,Y>
      Parameters:
      item - The item that has been removed from the series
      series - The series the item was removed from

    • dataItemChanged

      protected void dataItemChanged(XYChart.Data<X,Y> item)
      Called when a data item has changed, ie its xValue, yValue or extraValue has changed.
      Specified by:
      dataItemChanged in class XYChart<X,Y>
      Parameters:
      item - The data item who was changed

    • seriesAdded

      protected void seriesAdded(XYChart.Series<X,Y> series, int seriesIndex)
      Description copied from class: XYChart
      A series has been added to the charts data model. This is where implementations of XYChart can create/add new nodes to getPlotChildren to represent this series. Also you have to handle adding any data items that are already in the series. You may simply call dataItemAdded() for each one or provide some different animation for a whole series being added.
      Specified by:
      seriesAdded in class XYChart<X,Y>
      Parameters:
      series - The series that has been added
      seriesIndex - The index of the new series

    • seriesRemoved

      protected void seriesRemoved(XYChart.Series<X,Y> series)
      Description copied from class: XYChart
      A series has been removed from the data model but it is still visible on the chart. Its still visible so that you can handle animation for removing it in this method. After you are done animating the data item you must call removeSeriesFromDisplay() to remove the series from the display list.
      Specified by:
      seriesRemoved in class XYChart<X,Y>
      Parameters:
      series - The series that has been removed

    • layoutPlotChildren

      protected void layoutPlotChildren()
      Called to update and layout the plot children. This should include all work to updates nodes representing the plot on top of the axis and grid lines etc. The origin is the top left of the plot area, the plot area with can be got by getting the width of the x axis and its height from the height of the y axis.
      Specified by:
      layoutPlotChildren in class XYChart<X,Y>

    • getClassCssMetaData

      public static List<CssMetaData<? extends Styleable,?>> getClassCssMetaData()
      Gets the CssMetaData associated with this class, which may include the CssMetaData of its superclasses.
      Returns:
      the CssMetaData
      Since:
      JavaFX 8.0

    • getCssMetaData

      public List<CssMetaData<? extends Styleable,?>> getCssMetaData()
      This method should delegate to Node.getClassCssMetaData() so that a Node's CssMetaData can be accessed without the need for reflection.
      Specified by:
      getCssMetaData in interface Styleable
      Overrides:
      getCssMetaData in class XYChart<X,Y>
      Returns:
      The CssMetaData associated with this node, which may include the CssMetaData of its superclasses.
